Published Mar 21, 2024
CWE ID 488


CVE-2024-27935 is a vulnerability in Deno, a JavaScript, TypeScript, and WebAssembly runtime. The vulnerability exists in versions 1.35.1 and prior to 1.36.3, where there is a risk of cross-session data contamination during simultaneous asynchronous reads from Node.js streams sourced from sockets or files. This occurs due to the re-use of a global buffer (BUF) in stream_wrap.ts, which can lead to data intended for one session being received by another session, potentially causing data corruption and unexpected behavior. All users of Deno that utilize the node.js compatibility layer for network communication or other streams may be affected by this vulnerability. The issue has been patched in version 1.36.3, which provides a solution to remediate the vulnerability.
